TECHNICAL FIELD

The present invention belongs to the field of electronic nebulizers, and more particularly, relates to an integrated sealed micro-mesh nebulization module.

BACKGROUND

Nebulizer treatment has a principle of nebulizing a medicine into micro droplets, and the atomized liquid is inhaled into a human body by respiration to achieve a therapeutic effect. In this way, not only pain of taking the medicine is alleviated, but also waste of the medicine caused by a process of taking the medicine is avoided, and the therapeutic effect of the medicine is also able to be fully exerted. A nebulizer has many functions in medical treatment, comprising anti-inflammation, cough relief, phlegm elimination, bronchospasm relief, smoothing of airway and improvement of ventilation, so that a patient may not feel dyspnea during treatment. The nebulizer may also be used before and after chest surgery to prevent respiratory tract infection, so that the surgery may have good a result, and the nebulizer may be used in treatment of lung cancer with an anticancer medicine. A micro-mesh nebulization sheet is an important part of a micro-mesh nebulizer, which is mainly made of a metal mesh and a ceramic material. The micro-mesh nebulization sheet oscillates at a certain frequency under driving of a circuit, so that a ceramic vibrating reed oscillates resonantly, thus driving the metal mesh to oscillate at a high speed. Therefore, a liquid medicine passes through numerous micro-mesh openings in the metal mesh and is quickly ejected to form countless atomized micro particles. However, the nebulization sheet in the market now usually needs to be purchased separately, and a series of problems such as clamping and fixing, sealing and waterproofing, circuit welding and so on may be encountered during assembly, thus greatly affecting a universality of the nebulization sheet. If the nebulization sheet needs to be disassembled, such as cleaning and sterilization, a nozzle and other connecting parts must be disassembled before performing routine maintenance on the nebulizer.

SUMMARY

In view of the above problem, the present invention is intended to provide an integrated sealed micro-mesh nebulization module, which is universal and convenient to mount, and facilitates sterilization and cleaning.

In order to achieve the above objective, the present invention provides an integrated sealed micro-mesh nebulization module, which comprises a nebulization device and a nozzle mechanism disposed on the nebulization device, wherein the nebulization device is detachably connected with the nozzle mechanism disposed on the nebulization device. The nebulization module comprises an annular base, a lower shell disposed in the annular base, an upper shell disposed on the lower shell, a micro-mesh nebulization sheet disposed on the lower shell, a first sealing ring and a second sealing ring respectively disposed on both sides of the micro-mesh nebulization sheet, and a metal contact disposed between the lower shell and the upper shell, with one end connected with the micro-mesh nebulization sheet through a wire, and the other end extending to an exterior of the lower shell and connected with an external driving circuit. A first through hole is disposed in a center of the upper shell, and a second through hole corresponding to the first through hole is disposed in a center of the lower shell. The nozzle mechanism comprises a bottom cover disposed on one side of the upper shell in the annular base, a tubular spout disposed on the bottom cover, and gas outlets for discharging excess atomized gas respectively disposed on the bottom covers at upper and lower sides of the spout. The bottom cover is provided with a central hole corresponding to the first through hole. Therefore, the upper shell, the first sealing ring, the micro-mesh nebulization sheet, the second sealing ring and the lower shell are connected in sequence to form a sealed and closed state, so that gas generated by liquid flowing through the second through hole on the micro-mesh nebulization sheet may be sprayed out from the spout through the first through hole and the central hole in sequence, and excess gas is discharged from the gas outlet. In addition, an I-shaped sealing ring is used as the second sealing ring.

In some embodiments, an edge of the upper shell is provided with an annular bulge serving as an ultrasonic line.

In some embodiments, the lower shell is provided with a first threaded hole and a second threaded hole for connecting the bottom cover.

In some embodiments, the gas outlet is an arc-shaped port, and a shielding portion is disposed at an edge of the port for discharging gas inside the spout and preventing an external foreign matter from entering the spout. Therefore, not only the atomized gas generated inside the spout may be discharged to the outside from the gas outlet, but also the external foreign matter may be prevented from entering the spout to cause pollution through this hidden-type design.

In some embodiments, a first gas channel is further provided at an inner wall of the spout, the nebulization device is also provided with a second gas channel corresponding to the first gas channel, and the first gas channel is communicated with the second gas channel.

In some embodiments, a limiting groove and a limiting bulge are respectively provided at a contact surface between the upper shell and the lower shell.

The present invention has the beneficial effects of being universal and convenient to mount, and facilitating sterilization and cleaning. Since the upper shell, the first sealing ring, the micro-mesh nebulization sheet, the second sealing ring and the lower shell are connected, extruded and fixed together in sequence by ultrasonic welding, the micro-mesh nebulization sheet is electrically connected with the metal contact, and the metal contact is externally connected with the driving circuit, so that the micro-mesh nebulization sheet and the components thereof are modularized to form an nebulizing unit, thus improving a universality of the nebulization sheet. Moreover, an extension portion of the lower shell is provided with the first threaded hole for connecting the nebulizing unit with the nozzle; the bottom cover of the nozzle is provided with the second threaded hole for connecting the nozzle with an nebulizer body; and the gas outlet is disposed at an adjacent position between the spout and the bottom cover for discharging the excess atomized gas. In this way, the nebulizing unit is mounted on the nozzle to form the integrated nebulization module, and then the nebulization module is mounted on the nebulizer body, so that the nebulizing unit can be disassembled by disassembling the nozzle, thus facilitating cleaning and sterilization of the nebulization sheet.

In addition, the I-shaped sealing ring is used as the second sealing ring, so that the corresponding sealing ring can be omitted at a contact portion between the lower shell of the nebulizing unit and the nebulizer body, and a structure of a joint among the components is simpler while being waterproof, so as to prevent misplacement, dropping, loss and so on of the parts. Therefore, the present invention not only improves the universality of the nebulization sheet, but also can disassemble the nebulizing unit by disassembling the nozzle, thus further facilitating cleaning and sterilization of the nebulization sheet.
